Getting ready for your BCBA exam? You’re in the right place.

I created RBTExamPrep.com to give you the most realistic BCBA mock exam experience possible 185 questions designed to feel just like the real thing.

My goal isn’t just to help you pass, but to help you understand every concept deeply.
Whether you get a question right or wrong, you’ll see detailed feedback explaining why, so you’ll be ready for that type next time. I want you to walk into test day feeling confident, calm, and prepared.

Many students have shared that these questions felt almost identical to the real exam and that’s exactly what I was aiming for. I’d love to hear how you did please share your score in the comments below! It really helps encourage others who are preparing for the exam. 🙂

I built this site to keep high-quality BCBA prep resources free and accessible for everyone, which is why it’s supported by ads. If it helped you, it’d mean a lot if you shared it with your peers.

If you want to keep practicing, check out the BCBA section for more tests and study materials!

#1. A behavior analyst is consulting on a case where an adult client rigorously avoids eating shellfish, despite never having experienced an allergic reaction or illness from it. The client recalls their grandmother frequently telling them, If you eat shellfish, you’ll get very sick and have to go to the hospital. This verbal statement, made years ago, consistently influences the client’s dietary choices, even in the absence of any direct aversive consequences. What type of behavioral control best describes the client’s avoidance of shellfish?

Contingency-shaped behavior

Respondent conditioning

Prompt control

Rule-governed behavior

Rulegoverned behavior is behavior controlled by a verbal statement a rule rather than by direct contact with the reinforcement or punishment contingencies In this scenario the clients avoidance of shellfish is controlled by the grandmothers verbal statement even though the client has never directly experienced the negative consequences getting sick This distinguishes it from contingencyshaped behavior which is directly influenced by the history of reinforcement and punishment It is not respondent conditioning as avoiding shellfish is an operant behavior and its not simply prompt control because the behavior persists over a long period without the immediate presence of the prompting verbal stimulus
